Hagerty, Elkhart, Ind., assignor to The Adlake Company, Elkhart, Ind., a corporation ol Illinois Application January 26, 1951, Serial No. 207,979 Claims. (Cl. 189-76) This invention relates to metal window constructions and is more vparticularly concerned withv improvements iny a fire underwriters window.

It is a general object of the invention to provide a double sash window which is fabricated of metal members assembled and connected together to provide a rugged construction and which will withstand considerable heat without appreciable buckling or separation of the members.

It is a more specific object of the invention to provide a window of metal frame construction which when glazed with wire glass will be sumciently rugged to prevent a substantial blaze from penetrating the same and which will not be penetrated by any substantial amount of water from a conventional fire hose directed against it after it has been subject to such a blaze for a predetermined length of time.

It is a further object of the invention to provide a metal window construction formed of built up section which are readily assembled and connected together in a simple and eicient manner and with a minimum of manufacturing equip ment.

It is another object of the invention to provide in a` window of the type described having horizontal and/or vertical muntins which muntins are fabricated from two plate sections, one of the sections being bent along axial lines to form a member which is T-shaped in cross section with the margins of the material forming the stem and with screw holes formed in the stem. by separating the walls thereof to provide a circular .shape and spot welding on each side thereof, the

holes so formed being threaded to receive retaining screws which secure the other plate section thereto, which other section is bent along axial lines to provide a member having a central longitudinal recess therein for receiving a marginal portion of the stem of the 'lf-shaped section and having side ange portions cooperating with the top portions of the T-shaped section-to form therewith glass receiving channel formations or glazing recesses.

It is another object of the invention to provide in a double sash window a meetingfrail for the upper xed sash which is fabricated from two bent plate sections, one section being formed to provide an outer member having a channellike cross section with the margins of the plate material extending downwardly and vinwardly along the side `walls thereof and terminating in inwardly directed spaced flange formations intermediate the top and bottom edges. of the side walls, and with the other plate section being formed to -provide an inner member having a smaller channel-likecross section with the marginsof the material extending outwardly of Athe' ends of the side walls and adapted to be positioned in juxtaposed relation with the inwardly directed marginal ange formations of the outer member and with clinched interlocking tongue and slot connections arranged therebetween to connect the members in assembled relation.

It is another object of the invention to provide a joint construction between the ends of the stationary meeting rail and a jamb which will allow the rail to expand with heat and still be anchored sol-idly to the jamb.

It is a further object of the invention to provide a fire underwriters window which is economical to manufacture and which is also suieiently rugged to meet all the rigid Underwriters requirements.

These and other objects of the invention will be apparent from a consideration of the window construction which is shown by way of illustration in the accompanyingdrawings, wherein:

Fig. 1 is an elevation of a window construction embodying the principles of the invention;

Fig. 2 is a vertical section taken generally on the line 2-2 of Fig. 1 and to an enlarged scale;

Fig. 3 isa cross section of a horizontal muntin in assembled condition with the section taken through one ofthe connecting screws;

Fig. 4 is a cross section similar to Fig. 3 at another point on the muntin;

Fig. 5 is an exploded perspective view of the members which form the muntin;

Fig. 6 is a transverse section through the bottom or meeting rail of the xed sash;

Fig.l '7 is a perspective view of a length of the bottom or meeting rail; and

Fig. 8 is a section taken on the lines 8-8 of Fig. l showing the joint construction between the meeting rail and the jamb.

- tudinal axis to 'Ihe window construction which is illustrated in the drawings is particularly adapted for use Where there are substantial fire hazards and has embodied therein the principal features of the invention.

Referring to Fig. 1, the illustrated window comprises a top sash I0 and a bottom sash I I, the top sash iB being relatively xed with respect to the window frame and the bottom sash I I being vertically movable relative thereto. The frame construction is characterized by side rails or jarnb` members I2, a bottom sill I3 and a top cross member or header I4. The various members of both the window frame and the sash frames are formed from metal plates or strips of relatively 'thin strong material such as stainless steel. Each of the frame members is fabricated from one or more plates by bending the plate material on lines extending along the longiform the desired structural cross section. v

The side and top members .of the upper fixed sash I are formed as an integral part of the jambs I2 and top cross member I4 which constitute main members'lofithe window fframe. The upper sash I0 also'includes a horizontal muntin i5 and a bottom cross member or meeting rail I5.

Each jiarnb member I2 is shaped to provide vertically extending inner and outertfaceiplates Il and I8 and a connecting web divided into three parallel oiset vertical portions '19, i2i) and S12-I which face inwardly of the *window'openng and connecting portions 22 and 23 which are parallel with face plates I1 and I8 andinispaced or-loffset relation. The margins of the connecting webare integral with the face. plates II and AI8 or'are joined thereto alo-ng lines intermediate the vertical side 'edges thereof.
